TILE-MOLDING MACHINE.

Specification of Letters Patent.

Patented April 2, 1907,

Application ne@ May 18,1906. serial No. 317,437.

T all whom t ma/y con/cern:

Be it known that I, DAVID LEONARD, a

citizen of the United States, residing at St. Louis, in the county ofGratiot and State of Michigan, have invented a new and usefulTile-Molding Machine, of which the following is a specification.

This invention relates to machines for molding tiles; and its object isto provide a mold of novel construction in which the material of whichthe tile is to be formed can be firmly packed or tamped and from whichthe molded object can be easily removed without danger of injurythereto.

A still further Objectis to provide a machine which is simple inconstruction and which can be easily and quickly operated.

` With the above and other objects in view the invention consists of atable in which is mounted a slidable core adapted to be readily raisedabove or dropped below the top of the table. The core when raisedprojects into a sectional jacket, one portion of which -is immovablymounted on the table, while the other portion is hinged to swing openand has means for fastening it when closed. A split casing formed,preferably, of thin sheet metal is adapted to iit snugly within thejacket and surround the raised core. The material of which the tile isto be formed is adapted to be tamped between the core and the casing,after which the core is withdrawn downward from the mold, the jacketopened, and the casing with the tile therein removed, after which saidcasing is opened and removed from the molded object.

The invention also consists of certain other novel features ofconstruction and combinations of parts, which will be hereinafter morefully described, and pointed out in the claims.

In the accompanying drawings is shown the preferred form of theinvention.

In said drawings, Figure 1 is a side elevation of the table, portionsthereof being broken away and showing the jacket open, the core of theVmold being shown by dotted lines in lowered position. Fig. 2 is a planview of a portion of a table and showing the closed mold thereon, andFig. 8 is a detail view of the casing with its ends disconnected.

Referring to the figures by characters of reference, 1 is a table-'topsupported by a suitable frame 2, in which is mounted a crossstrip 3,having a guide-opening 4 therein. A locking-lever 5 is fulcrumed at oneend upon l one side of the frame and extends under the cross-strip andis supported near its other end upon a guide 6, secured to the frame 2.A link 7 is pivotally connected to one end of the frame and constitutesthe fulcrum of a lever 8, which extends from the end of the frame and ispivoted at one end to a plunger 9, which is mounted to reciprocatewithin the opening 4. This plunger extends downward from and is securedto or formed with a core 10, which is mounted to reciprocate within anopening 11, formed in the table-top. The core may be formed entirely ofmetal or may be of wood with a metal covering.

Arranged upon the table and surrounding the opening 11 is a jacket 12.This jacket consists of a section 13, which is immovably secured to thetable, as by means of brackets 14, and a movable section 15 is hinged atone edge to the fixed section 13 and is adapted to be closedthereagainst, so as to completely surround the opening 11. A catch orlatch 16 is connected to the section 15 and is adapted to engage akeeper upon section 13, so as 8o to lock the jacket when closed. Acasing 1S, preferably formed of a sheet of thin metal, is adapted to fitsnugly within the jacket 12, and the ends thereof overlap and aresecured together in any preferred manner, as by means ofinwardly-extending lugs 19, formed at one end of the casing and adaptedto be seated in slots 20, formed in the other end.

When it is desired to mold a tile by means swingingthe member or section15 upon its hinges, and the core 10 is moved into position abovethetable by means of lever 8 and is locked in such position by swingingthe lever of this machine, the jacket 12 is opened by 9o 5 under the endof the operating-lever 8. 95

Casing 18 is placed around the core and its ends are locked together bymeans of lugs 19, after which the jacket is closed tightly about Vthecasing and locked. The material of which the tile is to be formed isplaced around 1 oo the core and within the casing and suitably tamped,after which the locking-lever 5 is pulled out of engagement with theoperatinglever and the core drops by gravity out of the mold. The jacketis then opened and the casing 1S, with the molded object therein, isremoved to a place where the tile may be dried, and the ends of thecasing are then disengaged, and said casing will move from the moldedobject. The casing can then be replaced in the mold and theabove-described operation then repeated.

IIO

By using a machine such as herein described a tile can be quickly formedand then removed for drying Without danger of being injured. Importanceis attached to the particular means for fastening the ends of the casingtogether, because they permit said ends to be easily assembled andquickly detached Without presenting any projections Which Will mar theappearance of the tile Whenriinished. By mounting the operating lever 8on a link any absolutely vertical movement of the core is permitted.

The preferred form of the invention has been set forth in the foregoingdescription but I do 4not limit myself thereto, as I am aware thatmodifications may be made therein Without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall Within the scope of the claims.

That is claimed is# l. A molding-machine comprising a table, acore'lpmounted to reciprocate therein, a ljacket mounted upon the tableand adapted to surround the core, said jacket consisting ofmovably-connected sections, one of said sections being immovably mountedupon the table, and a casing removably mounted Within the jacket andcomprising a single sheet adapted to surround material Within thejacket, the ends of said casing being adapted to overlap, and means uponsaid ends for holding them together When overlapping.

2. A molding-machine 'comprising a table, a core mounted to slidetherein, a sectional jacket with one of its sections immovably securedupon the table, the other section being movably connected to theimmovable section, a casing adapted to be seated within the jacket andformed of a single sheet adapted to surround material Within the jacket,one end of said sheet having apertures therein, lugs integral with theother end and adapted to be seated Within the apertures, a plungermovable With the core, a guide therefor, a link pivoted upon the table,a lever fulcrumed upon and movable with the link, one end of said leverbeing pivoted to the plunger, and a locking-lever mounted to swing intothe path of the first-mentioned lever wheny the core is raised.

In testimony that I claim the foregoing as my own I have hereto amxed mysignature in the presence of two Witnesses.

DAVID LEONARD.
